No, you would aim slightly above, because when you throw the spear and it travels through the air it will fall slightly downwards by the time it reaches the fish.

The electricity received at an electrical substation has a potential difference of 20,000 V. What should the ratio of the turns
iren2701 [21]

The turn ratio of the transformer is 40.

<h3 />

<h3>What is a transformer?</h3>

A transformer is an electrical device that is used to step up or step down voltage.

The formula for calculating the turns ratio of a transformer is given below.

<h3> Formula</h3>
  • a = V/v.......... Equation 1

Where:

  • V = Primary voltage
  • v = Secondary voltage
  • a = Turns ratio of the transformer

From the question,

Given:

  • V = 20000 V
  • v = 500 v

Substitute the values above into equation 1

  • a = 20000/500
  • a = 40.

Hence, The turn ratio of the transformer is 40.

In a $100$ meter track event, Alice runs at a constant speed and crosses the finish line $5$ seconds before Beatrice does. If it
Liono4ka [1.6K]

Answer:

10s

Explanation:

If it took Beatrice 25 seconds to complete the race

Distance = 100 meter

Beatrice speed = 100/25

                          = 4m/s

If Alice runs at a constant speed and crosses the finish line $5$ seconds, she must have completed the race in 20s (25 -5).

Her speed where constant

= 100/20

= 5 m/s

It would take Alice

= 50/5

= 10s

It would take Alice 10s to run $50$ meters.

The components of a 10.8-meters-per-second velocity at an angle of 34.° above the horizontal are
Kisachek [45]

Answer:

6.0 m/s vertical and 9.0 m/s horizontal

Explanation:

For the vertical component, we use the formula:

  • Sin(34°) = <em>y</em> / 10.8

Then we <u>solve for </u><u><em>y</em></u>:

  • 0.559 = <em>y</em> / 10.8
  • <em>y </em>= 6.0

And for the horizontal component, we use the formula:

  • Cos(34°) = <em>x</em> / 10.8

Then we <u>solve for </u><u><em>x</em></u><u>:</u>

  • 0.829 = <em>x</em> / 10.8
  • <em>y </em>= 9.0

So the answer is " 6.0 m/s vertical and 9.0 m/s horizontal".
